This invention relates to firearms for personal defense, and particularly to one employingeither a gas or lead cartridge and which may be secured in concealed position to the. arm of the user and fired upon certain movements of the arm and one of the wearers fingers.

An important object of this invention is the provision of a firearm which may be concealed beneath and within the sleeve of a garment of the wearer and be fired by movement of the wearers finger.

Affurther object of this invention is the provision of a mounting element for a compact gun or the like, and having means slidably mounted thereon which, when actuated by movement of the finger, will cause the i cartridge to be fired.

A further object of the invention is the provision of a weapon for self-defense which willbe inexpensive to manufacture, efiicient and safe in operation, and which will comprisea small number of parts.

Other and further important objects of this invention will be apparent from the disclosuresin the specification and the accompanying drawing.

"This invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described.

On the drawing:

. Fig.1 is a top plan view of my firearm showing means whereby the same may be fastened about the arm and showing the structural features in detail; I

r Fig. 2 is a side elevational View taken on line II-II of Fig. 1.

Fig. 3 is an enlarged fragmentary view of the slidable rack bar and means for normally holding the same in projected position. a

Fig. 4 is a cross sectional view with parts broken away showing the interior of the cartridgegun.

,As shown on the drawing: t The reference numeral 10 indicates a strip of flexible leather or other similar material which is of the size adapted to pass around the fore arm of a wearer. A substantially rectangular mounting plate 11 of metal having corner apertures is secured in substantially central position on the surface of said leather strip 10 by bolts12 which pass through the corner apertures of said mountthe leather strip 10, and the apertured ends of said straps pass through slots at one side of said leather strip to be conveniently buckled on the opposite side of the fore arm,

and in a position so that the gun barrel will point beneath the palm of the hand.

A metal U-shaped channel member 13 is secured by welding or the like with its back surface upon the mounting plate 11 and in a position sothat its flanges 14 and 15 extend perpendicularly to. said mounting plate. The flange15 has one end thereof turned at right angles to forma guard 16 for a purpose which will hereinafter appear. The portion of the upper edge of the opposite end of the flange 15 is turned horizontally and downwardly to form a housing 17 which incloses spring means, as will be later described, and in which is slidably mounted one end of a slidable rack bar 18, the slidable rack bar having a horizontally extending abutment 19 at one end and having an opposite reduced end 20 about which is mounted one end of the coil spring 21 which is inclosed within the housing 17. The outer end of the housing 17 is .closed except for a threaded aperture in whichis threaded a screw 22 which holds the spring.21 in place and provides convenient means whereby saidspring may be removed.

A gear wheel 23 having a prolonged shank 24 is rotatably mounted on the bolt 25 which ger of the wearer, the flexible cable 28 being of such length sothat bending of the wearers hand at the wrist away from a sutstantially straight position will cause said gear wheel 23 to be rotated to slide the rack bar 16, which comprises the means for releasing a cartridge firing element which will now' be described.

c The cartridge exploding device which may be employed in connection with my invention may be either a conventionalforinof gun which may be secured to the mounting plate 11, but my preferred formcomprises a tubular housing 30 which has its open end in ternally threaded and which is secured to the flange 15 and ltby welding or the like. A metal gun barrel 31 which is bored for the conventional reception of a standard cartridge has its loading end externally threaded, whereby said barrel 30 may be threadingly secured and removable from the tubular housing 30 to permit replacement of the cartridge; The gun barrelBl is preferably of a length extending beyond the periphery of the mounting plate 11, as shown in Figs. 2 and 3.

A slidable metal plunger 32 having an in.

tegral centrally disposed firing pin is adapted to slide in said tubular housing 30, the

slidable movement thereof being limited by a stud 33 which has one. end preferably threaded in perpendicular position in the slidable plunger 32, the main portion of said stud extending through and projecting abovean elongated angular shaped slot 34 formed in the wall of the tubular housing 17. Said slot 34 terminates in a rightangle to form a pronounced shoulder 35 which is adapted to engage the stud 36 to hold the plunger in retracted positionyas shown in Fig. 1.' A coil spring 38 is disposed between the rear end ofthe plunger 32 and the closed end of the tubular housing 30, said spring being adapted to quickly force the plunger 32 and firing pin 37, when released, to fire a cartridge in the barrel 31.

It will be apparent that when loading the gun the plunger 32 will be drawn back manually by pulling backward the projecting stud 36 and engaging the same behind the shoulder 35 of the tubular housing 30.

The flexible leather strip 10 comprising the sleeve is adapted to'be fastened about the fore arm and secured in such position by means of .a pair of leather straps 39 which have suitable buckles and apertures at the opposite ends of said straps. The sleeve member 10 is fastened about the fore arm in a position so that the concealed weapon and device hereinbefore described will be. on the under side of the arm and the gun buckle 31 will point below the inside of thepalm. The ring 29 will be slipped over'one of the fore fingers a specific effort to do so, which will overcomethe. aetionof the spring 21 and cause a. cartridge to be fired as hereinbefore described a-nd in a direction toward which the wearer points his arm.

I am aware that'ma-ny changes may be made and. numerous details. of the. invention and construction-thereof may be varied; through. a wide range without departing "from. the principles of this inventionpand' I therefore do not desire to limit the; patent granted thereon otherwise than necessitatedby the prior art. 7 r

I claim as my invention:

1. In a device of theclass described, a frame a rack bar slidably mounted. on-said. frame; an abutment on one end of-said rack bar; a gear wheel pivotally mounted'on said frame and in mesh with said rack bar alever secured on said gear wheel, and a cartridge exploding device mounted in saidv frame and having a trigger, the movement of said gear wheel beingadapted to movesaidrack bar torelease said trigger. l

2. Incombination with acartridgeexploding device comprisinga barrel, a slidable pisl that the wearer will bendhis hand into such a position only upon ton and impelling spring and a.tr1-gger';,a
